1. PHP实现：

$port = 11211;$host = '192.168.11.128';$mem  = new Memcache();$mem->connect($host, $port);$items = $mem->getExtendedStats('items');$items = $items["$host:$port"]['items'];foreach($items as $key => $values){$number = $key;$str = $mem->getExtendedStats ("cachedump",$number,0);$line = $str["$host:$port"];if(is_array($line) && count($line) > 0){foreach($line as $key => $value) {echo $key . '=>';print_r($mem->get($key));echo "\r\n";}}}

2. Java实现：

import java.io.IOException;import java.net.InetAddress;import java.net.InetSocketAddress;import java.util.Iterator;import java.util.Map;import java.util.Map.Entry;import java.util.concurrent.TimeoutException;import net.rubyeye.xmemcached.KeyIterator;import net.rubyeye.xmemcached.MemcachedClient;import net.rubyeye.xmemcached.XMemcachedClient;import net.rubyeye.xmemcached.exception.MemcachedException;public class XMemcache {public static void main(String[] args) throws IOException, TimeoutException, InterruptedException, MemcachedException {InetAddress addr = InetAddress.getByName("192.168.11.128");InetSocketAddress ia = new InetSocketAddress(addr, 11211);MemcachedClient client = new XMemcachedClient(ia);KeyIterator it = client.getKeyIterator(ia);while(it.hasNext()) {String key = it.next();System.out.println(client.get(key));}client.shutdown();}}

特别提醒：http://fnil.net/docs/xmemcached/net/rubyeye/xmemcached/class-use/KeyIterator.html

memcached 1.6.x will remove cachedump stats command,so this method will be removed in the future
